Gaza, ALRAY -- The United Nations Relief and Works Agency for Palestine Refugees (UNRWA) will launch on Monday a funding campaign to face its budget deficit, said UNRWA’s media advisor, Adnan Abu Hasna.

Abu Hasan said that "UNRWA Commissioner-General Pierre Krahenbuhl will hold a press conference in Gaza on Monday where he will announce the kick-off of the campaign."

In the conference, Krahenbuhl will send a message to the international community to start a funding campaign to help UNRWA continue providing its services to the Palestinian refugees.

"The agency is facing unprecedented challenges," Abu Hasna said.

The campaign comes days after the United States decided to decrease its contribution to UNRWA in 2018 from 125 million U.S. dollars to 65 million dollars.

US President Donald Trump has recently threatened to reduce aid to the Palestinians if they refuse to return to the negotiation table with Israel.

The U.S. administration has also announced it will not provide the agency with 45 million dollars for aid that it pledged in December last year.

The United States donates annually 364 million dollars to UNRWA, making it the largest sole contributor to the UN agency.

UNRWA, which provides assistance in education, health and food to some 5 million registered Palestinian refugees in the Middle East, is already suffering from a 49-million dollars financial deficit and any fund suspension would have a negative impact on its work.
